| 摘 要： | 通过对黄颡鱼的全长(L)、最大周长(Mc)、最大体高(Mh)和最大头宽(Mw)的测定，得出黄颡鱼全长与最大周长、全长与最大体高、全长与最大头宽间均呈直线线性相关。全长(L)与最大周长(Me)间的相关方程为：Me=0．3542 0．4861L(r=0．9758)；全长(L)与最大体高(Mn)间的相关方程为：Mn=0．1389 0．1503L(r=0．9649)；全长(L)与最大头宽(Mw)间的相关方程为：Mw=0．1085 0．1424L(r=0．9709)。根据所求得的相关直线方程，得出各自的95％上下可信限，通过比较、分析，得出网箱养殖黄颡鱼时网目尺寸大小确定的公式为2a=0．139 0．15L。

| Abstract: | This paper studied on the correlation among the body - length and maximum perimeter, and body - height, and head - width of P. fulvudraco. The regression analysis showed that there were linear relationships among the body - length and the maximum perimeter, and body - height, and head - width respectively. The linear regression equations among body - length and the maximum perimeter, and body-height, and head - width were Mc =0. 3542+0. 4861L(r = 0. 9758), Mh=0. 1389+0. 1503 L (r = 0.9649), Mw = 0. 1085 + 0. 1424 L (r = 0. 9709), separately. The respective regression 95% confidence was made according to the above linear regression e-quation. Based on the comparison and analysis, the correlate equation between the body - length of P. fulvudraco and the size of the mesh was summarized as follows: 2a =0. 139 +0. 150L |
